AMD Ryzen AI 9 HX 375 vs Intel Core i9-14900T Comparison

The Verdict

The Intel Core i9-14900T is the stronger overall processor according to the database’s average benchmark score, posting a 51015 average against the AMD Ryzen AI 9 HX 375’s 46030. That is a 10.8% gap in aggregate performance, and the Intel part also holds a higher percentile rank, sitting at 90 versus the AMD’s 89. The head-to-head results are even more lopsided: the i9-14900T wins 13 of the 15 recorded tests, while the Ryzen AI 9 HX 375 takes only 2.

The verdict from the data is clear for users who need maximum compute throughput in a desktop context: the Intel Core i9-14900T delivers consistently higher scores across rendering, encryption, compression, and math workloads. Its Cinebench R23 multi-core score of 30803 versus the AMD’s 21812 represents a 29.2% advantage, and the single-core gap is even larger at 54.3% in favor of Intel. The i9-14900T is the pick for heavy multithreaded work and any task that relies on high single-thread performance.

The AMD Ryzen AI 9 HX 375, however, is not without its own merits. It wins the Cinebench R15 multi-core test with a 7.4% margin (3334 versus 3104) and the PassMark extended instructions test with a 23.7% margin (29269 versus 23660). Those two wins point to specific strengths in certain legacy rendering workloads and instruction-set extensions. For a mobile processor with a 28 W TDP, the Ryzen AI 9 HX 375 also shows competitive results in some integer and string operations, trailing by single digits in several categories. The data suggests the AMD part is the better choice for a power-sensitive mobile platform where the two winning workloads matter, while the Intel part dominates everywhere else.

The pattern is consistent: the Intel i9-14900T leads in nearly every category, with particularly large margins in single-core and multi-core rendering. The AMD’s two wins, while smaller in number, are meaningful in their respective workload categories.

Where Each One Wins

The Intel Core i9-14900T is the dominant choice for rendering workloads. Its Cinebench R23 multi-core score of 30803 is 29.2% higher than the AMD’s 21812, and its single-core score of 4348 is 54.3% higher. For users running CPU-based rendering, video encoding, or any task that scales with Cinebench-style performance, the Intel part is clearly ahead.

The Intel part also wins in data compression and encryption. It scores 436066 in data compression versus 404918, a 7.1% margin, and 27062 in data encryption versus 20802, a 23.1% margin. These results indicate an advantage in file archiving, database workloads, and encryption-heavy tasks. The Intel part also leads in prime number finding (164 versus 122, 25.6%), floating point math (92699 versus 75153, 18.9%), and integer math (138149 versus 121754, 11.9%), which points to general scientific and financial computing strength.

The AMD Ryzen AI 9 HX 375 wins the Cinebench R15 multi-core test with a 7.4% margin, which indicates that certain legacy rendering workloads may run better on the AMD platform. Its other win is in PassMark extended instructions, where it scores 29269 versus 23660, a 23.7% margin. This suggests the AMD part has an advantage in workloads that use specialized instruction sets, such as SIMD-heavy or cryptography-related code that relies on newer extensions.

For power-sensitive mobile use, the AMD part’s 28 W TDP versus the Intel’s 35 W TDP is a relevant distinction, though the Intel part still delivers higher performance in most tests. The AMD’s wins, combined with its lower TDP and mobile socket, position it as the choice for a compact or battery-powered system where the two winning workloads are prioritized. The Intel i9-14900T, with its desktop socket, higher TDP, and 13 benchmark wins, is the choice for maximum performance across the broadest set of tasks.
